I'm not sure what the actual failure is about, but the panic above is due to calling require.NoError in a background goroutine, which is not allowed.

[zmb3]

There's also a data race due to overwriting err from inside a goroutine, and a goroutine that runs an infinite loop that never terminates.

Got a new failure here, it seems we are failing the test outside of the main goroutine again https://github.com/gravitational/teleport/actions/runs/4493152265/jobs/7903987200?pr=23416

Likely still flaky, but disabled in #23428
